List of garbage disposals fully made of stainless steel

Most garbage disposals have stainless steel grinding components but most do not have a stainless steel grinding chamber. The grinding chambers of most disposals are either high-quality plastic or galvanized steel. But are there any garbage disposals fully made of Stainless steel? Ya, there are, and they are pretty expensive too.

Stainless steel is very resistant to corrosion and hence is durable. But it is also costly. So those disposals which are made of stainless steel are the top end models, and so far only the Evolution series by InSinkErator have them.

So here is the list of stainless steel garbage disposals;

1. InSinkErator Evolution Excel
